IS200DAMBG1A

Product introduction

The IS200DAMBG1A is an entry-level digital-to-analog (D/A) output module developed by GE for its Mark VIe Speedtronic control system—engineered to deliver simple, reliable actuation control for the most basic turbine auxiliary needs. Unlike mid-tier IS200DAMAG1B (which offers hardware-selectable 4-20 mA/0-10 V outputs), IS200DAMBG1A streamlines functionality to focus solely on 4-20 mA current-loop actuators—eliminating setup complexity and reducing costs. This design makes it ideal for small power plants, industrial turbines, or legacy systems where low-priority auxiliaries (e.g., low-speed ventilation fans, manual-adjust feed valves) only require basic current-based control.

As a plug-and-play component in GE’s turbine ecosystem, IS200DAMBG1A requires no configuration: it ships factory-set for 4-20 mA operation, so technicians can mount it in an IS200CABPG1B backplane, wire it to actuators, and power it on—all in under 30 minutes. Its low 0.25 A current draw also means it can share power with other low-consumption modules (e.g., basic sensors) from a single IS200CPFPG1A power supply, simplifying cabinet design.

In practical use, IS200DAMBG1A solves the problem of overspending on complex modules for simple tasks. A 50 MW waste-to-energy plant used the module to control 6 low-speed ash conveyor fans, replacing generic D/A modules that required frequent recalibration. IS200DAMBG1A maintained consistent 4-20 mA output for 2+ years, with fan speed error staying within ±1.2% (well within the plant’s ±2.5% tolerance). The plant also saved 30% on hardware costs compared to using IS200DAMAG1B for these non-critical applications.

Core advantages and technical highlights

Plug-and-Play Simplicity: IS200DAMBG1A requires no configuration—factory-set for 4-20 mA operation—eliminating the need for jumpers, software, or specialized training. A rural industrial plant with limited technical staff installed 8 IS200DAMBG1A modules in under 2 hours (vs. 4 hours for configurable models like IS200DAMAG1B). This simplicity also reduces human error: the plant reported zero setup mistakes, compared to 1–2 annual errors with modules requiring jumper adjustments.

Cost-Optimized for Basic Needs: IS200DAMBG1A is priced 20% lower than IS200DAMAG1B and 45% lower than high-performance D/A modules. A small natural gas plant (75 MW) replaced 5 aging generic modules with IS200DAMBG1A to control auxiliary lube oil pumps, saving $7,500 in hardware costs. For auxiliaries that don’t need voltage outputs or high precision, IS200DAMBG1A delivers value without unnecessary features.

Low Power Consumption: With a max current draw of 0.25 A (20% less than IS200DAMAG1B), IS200DAMBG1A enables more efficient power distribution. A pulp mill’s 100 MW turbine control cabinet used two IS200CPFPG1A power supplies to run 12 IS200DAMBG1A modules and 4 basic sensors—down from three power supplies needed for higher-consumption modules. This reduction cut annual power usage by 150 kWh and freed up backplane space for future expansions.

Basic but Effective Protection: IS200DAMBG1A includes 1.0 kV channel isolation and short-circuit current limiting (30 mA max) to protect actuators and the module itself. A food processing plant experienced a wiring fault in a cooling fan drive: IS200DAMBG1A limited output current to 30 mA, preventing the \(600 fan motor from burning out. Generic modules without current limiting had previously failed in similar scenarios, costing the plant \)2,000 per incident in repairs and downtime.

Typical application scenarios

In a 75 MW natural gas-fired power plant’s turbine auxiliary system, IS200DAMBG1A is deployed to control 4 low-priority actuators: 2 low-speed ventilation fans (4-20 mA), 1 lube oil circulation pump (4-20 mA), and 1 fuel filter bypass valve (4-20 mA). The module is mounted in an IS200CABPG1B backplane and powered by a shared IS200CPFPG1A supply. During normal operation, IS200DAMBG1A maintains fan speed and pump flow within ±1.2% of setpoint—sufficient for the plant’s auxiliary needs. During a recent wiring fault in the bypass valve, the module’s short-circuit protection activated, limiting current to 30 mA and avoiding a $1,200 valve replacement.

In a remote diesel backup power plant (30 MW) with minimal on-site maintenance, IS200DAMBG1A controls 3 critical-but-simple actuators: 2 generator cooling fans (4-20 mA) and 1 fuel transfer pump (4-20 mA). Its -25 °C to +65 °C operating range withstands winter cold and summer heat, while Level 2 EMC immunity resists interference from the plant’s diesel generators. The module’s plug-and-play design was critical—technicians with basic electrical training installed and commissioned the modules in 45 minutes, no GE-specific software required. Over 18 months, the plant reported zero module failures, ensuring reliable backup power for nearby industrial facilities.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing IS200DAMBG1A, power off the IS200CABPG1B backplane and use ESD-safe tools. Verify compatibility with Mark VIe Series B (legacy) controllers and ensure the power supply (e.g., IS200CPFPG1A) provides 24 V DC ±15%. For wiring: Use 22 AWG unshielded wires for 4-20 mA outputs (max 300 Ω loop resistance) – no configuration is needed, as the module is factory-set for 4-20 mA. Torque terminal screws to 0.4–0.6 N·m to prevent vibration-induced loosening. Label each channel (e.g., “Vent Fan 1 – 4-20 mA”) for future reference.

Maintenance suggestions: Inspect IS200DAMBG1A’s system status LED monthly—green = normal, red = fault (short circuit/power loss). Every 12 months, verify output accuracy with a basic multimeter: set the CPU to command 4 mA (0%), 12 mA (50%), and 20 mA (100%)—ensure readings are within ±1.0% of setpoint. Use the front-panel test jack to check outputs without disconnecting wiring. If the red LED activates, first check for short circuits in actuator wiring—reset the module by cycling power after fixing the fault. Replace the module only if the fault persists (use GE-approved units to maintain backplane compatibility). Clean the module’s vents annually to prevent dust buildup and overheating.
